. SPECIFICATION forming part of Letters Patent No. 744,983, dated November 24, 1903.

Application filed April 6, 1903- Serial No. 151,282. (No model.)

To aZZ whom it may concern:

Beit known that I, GEORGE J. SMITH, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Car-Trucks, of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to the manner of connecting the axles to the truok-frame,whereby antifriction-journals are provided in a cheap, elfective, and durable manner.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claim.

Figure I is a detail top view part in section and illustrative of my invention. Fig. II is a side view partin vertical section. Fig.

III is an enlarged detail View part in section and part in elevation and illustrating the manner of connecting the journal-bearing housing to the truck-frame. Fig. IV is a perspective view of one of the straps that connect the antifriction-bearings to the truckframe. Fig. V is a detail perspective View of the truck-frame.

Referring to the drawings, 1 represents part of the truck-frame, 2 the axles, and 3 a pair 0 of the wheels.

at represents an antifriction journal-bearing fitting over the ends of the axles. I make no claim as inventor to this form of antifric- 1 tion journal-bearing, but claim only the mannor of connecting the bearings to the truckframe. This manner of connection consists of U-shaped straps 5, having outturned ends 6. The straps fit over the journal-bearings and their ends rest upon the upper faces of the frame of the truck, the outer ends of the straps 4o fitting against lugs or projections '7, formed on the truck-frame.

8 represents bolts projecting upwardly through the truck-frame and through the ends 6 of the straps, above which they are provided with coiled springs 9, which form a yielding hearing or connection between the straps and the truck-frame. The straps 5 fit in grooves 10, formed in the housing of the antifriction-bearing, and the housing has downwardly-projecting lugs or ears 11, that embrace the upper edge of the truck-frame, so that when the springs 9 are compressed by the movement of the car the housings cannot move laterally away from the truck-frame.

The construction provides for an inexpensive, durable, and substantial connection between the truck-frame and an antifriction journatbearing that receives the car-axles.
